It is respectively arranged on outside the both ends of electronic component 120.It is appreciated that in other embodiments, electronic component 120 and pad 130
Can rationally it be set according to the actual requirements in the particular location of circuit board 100.
CIS 200 is installed on installing zone 110.
Support 300 have first surface 310 arranged in parallel and second surface 320 and with first surface 310 and
The lateral wall 330 that second surface 320 connects.The printing opacity through first surface 310 and second surface 320 is offered on support 300
Hole 340.
Second surface 320 is posted by circuit board 100.CIS 200 and electronic component 120 are contained in support 300
Interior, pad 130 is located at outside support 300.In the present embodiment, the lateral wall of the side of support 300 is provided with boss 350, boss
350 are used to house the electronic component 120 on circuit board 100.CIS 200 and electronic component 120 are contained in respectively
In loophole 340 and boss 350.
The lateral wall of support 300 is provided with breasting face 360.Breasting face 360 is used for the welding for being bearing on focusing drive mechanism 500
Pin 510.Breasting face 360 is connected with first surface 310 and second surface 320, and is bearing on face 360 and is formed with first surface 310
First obtuse angle.In the present embodiment, two breasting faces 360 are respectively arranged on the both sides of boss 350.The number in breasting face 360 with
The number for welding pin 510 is corresponding.Two breasting faces 350 can also be distributed on the side relative with boss 340 of support 300.
In the present embodiment, first surface 310 caves in form plummer 370 around the part of loophole 340.Plummer
370 are used to carry optical filter 400.
Optical filter 400 is on plummer 370.It is appreciated that in other embodiments, optical filter 400 can also be set
End in focusing drive mechanism 500 close to support 300.
As shown in Fig. 1, Fig. 3 and Fig. 4, focusing drive mechanism 500 is on first surface 310.Focusing drive mechanism 500 has
There is welding pin 510.Welding pin 510 is posted by breasting face 360, and is welded pin 510 and welded close to one end of circuit board 100
It is connected on pad 130.In the present embodiment, drive mechanism 500 of focusing is voice coil motor.It is appreciated that in other embodiment party
In formula, focusing drive mechanism 500 can also be other actuating units, can control axial direction of the camera lens 600 along focusing drive mechanism 500
Move back and forth.
In the present embodiment, it is an inclined-plane to be bearing on face 360.Breasting face 360 forms the first angle with second surface 320,
First obtuse angle and the first angle are complementary.Welding pin 510 is posted by whole breasting face 360, is utilized so that being bearing on face 360
Rate is maximum.
It is substantially vertical relation due to welding pin 510 with the position relationship of support 300, if the first obtuse angle is excessive, weldering
When pin 510 is posted by breasting face 360, welding pin 510 needs to be occurred necessarily according to the concrete condition in breasting face 360
Deformation.In order to cause welding pin 510 to remain former as far as possible while reducing the first obtuse angle and applying thrust to welding pin 510
Shape.In the present embodiment, the first obtuse angle is preferably 95~105 degree, and the first angle is preferably 75~85 degree.Further, first
Obtuse angle is preferably 100 degree, and the first angle is preferably 80 degree.So as to which that welds that pin 510 can consolidate is posted by breasting face 360
On.
As shown in Figures 1 and 5, in other embodiments, being bearing on face 360 includes vertical portion 362 and inclined plane part 364.It is perpendicular
Straight portion 362 and the vertical connection of second surface 320.Inclined plane part 364 is connected with first surface 310 and vertical portion 362.Inclined plane part 364
The angle formed with first surface 310 is the first obtuse angle.Welding pin 510 is posted by vertical portion 362.In present embodiment
In, the first obtuse angle is preferably 95~105 degree, and further, the first obtuse angle is preferably 100 degree.Due to welding pin 510 be posted by it is perpendicular
In straight portion 362, therefore, the span at the first obtuse angle can be more than 90 degree and be less than 180 degree.
Because the angle that inclined plane part 364 and first surface 310 are formed is the first obtuse angle, so as to inclined plane part 364 and vertical portion
362 the second obtuse angles formed.When welding pin 510 is posted by vertical portion 362, relative to right-angle structure, the second obtuse angle can
To effectively reduce the thrust that it applies to welding pin 510.
Relative to embodiment as shown in Figure 4, although part welding pin 510 (with 364 corresponding part of inclined plane part)
It is not posted by breasting face 360, the utilization rate for being bearing on face 360 is relatively small.But the second obtuse angle produces to welding pin 510
The application point of raw active force closer to circuit board 100, application point move down can effectively reduce the second obtuse angle to welding pin 510 apply
The thrust added.
It is appreciated that when the first obtuse angle in embodiment as shown in Figure 5 is preferably 95~105 degree, pin is welded
510 can also be posted by inclined plane part 364 and vertical portion 362 simultaneously.
Camera lens 600 is assembled in focusing drive mechanism 500.
Due to the first obtuse angle for being bearing on face 360 and being formed with first surface 310 in above-mentioned support 300, relative to right angle knot
Structure, its thrust applied to welding pin 510 can be effectively reduced, be produced outwards so as to effectively avoid welding pin 510
Mobile trend, and then it is firm make it that welding pin 510 is connected with pad 130.Because welding pin 510 is connected with pad 130
It is firm, so that there is preferable electric property using the camera module 10 of above-mentioned support 300.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more specific and detailed, but simultaneously
Therefore the limitation to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for one of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
